CHLORINATING APPARATUS Filed March 29, 1929 2 Sheets-shea 2 In ventor J1? (filed/inland M Attorney Patented Apr. 1, 1930 PATENT OFFICE WILLIAM C. BLACKMOND, OF RANGER, TEXAS CHLORINATING APPARATUS Application filed March 29, 1929. Serial No. 350,975.

This invention relates to what is known as a chlorinating apparatus, that is, a structure made for dispensing chlorine for sterilization of domestic and commercial water supplies.

The improved apparatus is believed to be an especially advantageous contribution to this art, in that it is characterized by simplicity in construction, compactness and convenience in arrangement of parts, and efficiency in operation.

I aim particularly to provide a structure of this kind, wherein all of the materials employed are especially suitable in that they are substantially non-corrosive to chemical action of the chlorine. This renders the structure substantially indestructive in so far as the chlorine is concerned. It eliminates deterioration and lengthens the life of the apparatus,

2 making it substantially indefinite. This is a great advantage over otherapparatus of this kind, as those now in use are subject to rapid deterioration and excessive upkeep cost.

I aim further to provide a structure which is not complicated, one which possesses no delicate mechanisms, to require constant attention of a skilled mechanic, nor a large stock of spare parts.

I also propose an apparatus which is constructed so that the parts are easily accessible and interchangeable for quick repairs, one which is fool-proof, easily regulated, and not likely to develop obnoxious leaks.

In addition, I propose a structure which requires no pressure compensator or gas check valve, and there is no back pressure to retard a continuance of gas fiow. Incidentally, one

pound of chlorine, in the supply drum of thisapparatus, will serve the same purpose of operation, equally as well as a full drum.

It follows that I have evolved and produced a device which is inexpensive, not likely to deteriorate, simple, positive, and infallible in performance, one which has no interruption in service, and no cause for emergency or standby units, or skilled operators and mechanics.

In the drawings: 7 Figure 1 is a diagrammatic view, showing in section and elevation the complete apparatus as constructed in accordance with the present invention.

Figure 2 is a horizontal sectional view on the line 2-2 of Figure 1.

Figures 3, 4, and 5 are sections on the lines 3-3, 4-4, and 5-5 respectively of Figure 1.

The complete arrangement of parts may be well seen in Figure 1, and attention is therefore invited to this figure.

Here the reference character 1 designates a support, which is variously designated as a panel or an enclosure. It might well be in the form of a slab of material, but is preferably made in the form of a protective box in which the principal details of the mechanism are housed.

Supported on this panel is an inverted bottle like liquid container preferably made of glass. This is designated by the reference character 2, and is held in place by appropriate supporting bands 3 and 4 respectively. Fitted within the neck 5 is a plug 6 held in place by a screw cap 7. This plug has a series of passages formed therethrough. Having their upper ends extending into these passages are short coupling pipes 8, 9, and

10 respectively, these being associated with an appropriate attaching bracket 11. In alignment with the pipe 10 is an upstanding supply tube 12, which extends in through the container and terminates adjacent the top thereof. Supported on the upper end of this is an inverted shield and deflector 13, which acts as a guard and prevents the discharge of gas back through the tube. A hose 14 is connected with the pipe 10 and is in turnconnected with the liquid supply pipe 15. A control valve for the liquid is represented as. at 16. There is another control valve 17 at the top which regulates the flow of the liquid through the filling funnel 18.

Below this funnel and extending at right angles is a strainer equipped water supply pipe 19, having a control valve 20 arranged therein. Incidentally, it is to be stated that the container 2 is adapted to be filled With a liquid. This may be of any suitable nature and the normal fluid level is designated by the reference character 21. This terminates below the top of the container and provides what may be designated as a gas expansion space 22. If desired, ordinary hydrant water may be employed for supplying the container. Any other transparent liquid however, will do.

The reference character 23 designates a chlorine supply drum having the control valve 24 connected with the hose 25, which is in turn connected with the pipe 8. This supplies chlorine gas through a meter pipe or tube 26 which extends up and into the liquid in the container. The upper end of this is formed with a return bend or depending goose neck 27. This goose neck carries an automatically operable regulating dispenser or meter device which is generally designated by the reference character 28. This is the distinguishing part of the invention. It comprises a depending cylindrical shell 29, which is open at its bottom and provided with a cross piece or spider 30. This spider constitutes a stop for an inverted bulbous shaped casing 31 which is arranged for vertical sliding movement within the shell.

The reference character 32 designates vent and gas conducting tubes. These open at their upper ends through the crown portion of the shell and have their lower ends depending into a buoyant bulbous shaped receptacle 31.

The reference character 33 designates a gas effluent pipe whose upper end is in a plane with the normal fluid level and whose lower end is fitted into the stopper 6 and disposed in alignment with the pipe connection 9. The reference character 34 designates the gas conducting pipe which leads to and is connected with the body of water to be treated with the chlorine gas sent from the container 2 in measured quantities. The reference character 35 designates a siphon by-pass which comprises a pipe connected with the fluid supply pipe 15 and provided with a valve 36. On the discharge end is a nozzle 37 arranged Within the efliuent gas pipe 34 and intended to produce a suction for drawing the gas downwardly through the efliuent pipe 33.

The operation of the apparatus is as follows: The first thing to do is to fill the container with liquid, either water, kerosene oil, or any pale liquid heavier than gas. The container is filled up to the normal fluid line 21, thereby leaving a gas expansion space 22 at the top.

If desired, water may be used. The fluid is either poured down through the funnel 1.8, whereupon it passes down through the pipe 15 and the valve 16 is opened and through the hose 14 and up through the pipe 12 and beneath the shield 13. If the funnel is not desirable for use, the ordinary city supply pipe the device is ready for operation. Now the valve 24 which regulates the flowing gas from the drum 23 is opened and the gas flows through the hose 25 and the pipe 26 into the regulating dispenser or meter 28. As a liquid seal has been formed by the fluid, as the gas comes in, the pressure will increase and overcome the static or gravity weight of the liquid and force it down in the meter device. The gas will come in and How down through the liquid into the receptacle 31. Then, at a predetermined point, the seal is broken and the gas rapidly escapes up through the vent tubes 32. The gas being lighter than the liquid bubbles and rises to the surface of the liquid and into the chamber top.

When the gas is vented and starts to escape, its movement is accelerated by virtue of the liquid flowing back into the dispenser as it did originally when filling the dispenser. When the dispenser has refilled, which is almost simultaneous with the escaping of gas, the seal is again formed and as the gas is flowing constantly, the cycle is completed and the operation starts over again. Successive operation of cycles, which in a measure is the rate of flow, may be regulated, increased or decreased, by means of the control valve 24 of the gas drum.

It is obvious that the dispenser is the gist of the complete apparatus and each throb or pulsation represents a iven amount of gas and therefore enables the operator to determine the proper rate of flow in escape of the as. h The gas escapes through the pipes 33 when snflicient pressure is built up and its discharge into the body of water at a distant point is facilitated by the siphon by-pass 35. The valve 36 is opened and the water is allowed to drip slowly through the nozzle 37 into the pipe 34-, thus setting up a suction which draws the gas downwardly.

If desired instead, a pump suction (not shown) might be substituted for the siphon to facilitate the discharge of the gas in proper measured quantities.

It is understood that the liquid in the container remains permanent and does not move out with the gas. It acts only as a medium for the proper functioning of the meter and it is replenished occasionally when evaporation may have lowered the normal level to an abnormal point.

It is thought that by considering the description in connection with the drawings, a clear understanding of the construction and method of operation of the invention will be had. Therefore, a more lengthy description is regarded as unnecessary.

Minor changes in the shape, size and rearrangement of details coming within the field of invention claimed may be resorted to, in actual practice, if desired.
